I agree with the point you are making, but I disagree with the wording you
use. The result of calling sort() with key=len *is* sorted. It is sorted by
length of the word.
Same for calling max() with a key. The result is still the maximum value.
The difference is how you decide which of two elements is greater:
max(list_of_foods, key=calories)
max(list_of_foods, key=weight)
max(list_of_foods, key=cost)
That is three different ways to decide which is the maximal food in the
list: by number of calories, by weight, or by cost.
